The invention relates to a brake booster (10) for a motor vehicle brake system, comprising a force input member (12) that is or can be coupled to a brake pedal and can be moved along a movement axis (V), a control valve (14) that can be actuated according to a movement of the force input member (12), a chamber arrangement (20) that is disposed in a booster housing (18), can be controlled by the control valve (14), and is provided with at least one negative-pressure chamber (28, 30) and at least one working chamber (24, 26) which are separated from each other by at least one movable wall (32, 34) coupled to the control valve (14), and a force output member (42) for applying a braking force to a downstream master brake cylinder arrangement. The control valve (14) is biased in a starting position along with the force output member (42) by means of a restoring spring (48), a first end of which rests on the control valve (14). According to the invention, the booster housing (18) includes a receiving opening (50) for the downstream master brake cylinder arrangement (58), said opening (50) being provided with at least one axial guiding section (56) and at least one radial stop section (54) which are designed to support a second end of the restoring spring (48).
